I am afraid at present it is not possible to set the default selected range of the Kendo UI RangeSlider via the data attributes. We will do our best to address this limitation as soon as possible. Please excuse us for the inconvenience caused.

I am glad to inform you that with Kendo UI Q3 2012 SP1 (v.2012.3.1315) the discussed functionality is already available. You can set the selected range on the slider using data-selection-start="//..." and data-selection-end="//...". For example:
